ENVELOP-SEAL.

Specification of Letters Patent.

Patented J an. 6, 1914.

Application filed March 8, 1912. Serial No. 682,491.

To all whom it may concern Be it known that I, WILBUR J. RINGER, acitizen of the United States, residing at Newberry, in the county ofNewberry, State of South Carolina, have invented certain new and usefulImprovements in Envelop- Seals; and I do hereby declarethe following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to new and useful improvements in seals forenvelops or the like.

An object of this invention is the provision of an envelop seal which isso constructed that the closing flaps will be locked to the lower flapsand held against any unsired displacement.

A further object of this invention is to improve and simplify devices ofthis character, rendering them comparatively simple and inexpensive tomanufacture, reliable and eflicient in use and readily operated.

A still further object of this invention is the provision of a keepermember for the latch in the envelop fastener which by reason of itsconstruction and disposition will act at once as a keeper for said latchand as clamping jaws for maintaining the several flaps of the envelop insecure assembled relation.

WVith the above and other objects in view, this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawing, in which:

Figure 1 is a rear elevation of an envelop having my invention appliedthereto and showing the closing flap in open position. Fig. 2 is atransverse sectional view showing the envelop in its closed position.Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2.

Referring to the accompanying drawing by similar characters of referencethroughout the several views, the numeral 10 designates generally anenvelop which comprises the usual body portion 11 having formed upon itsend edges the end flaps 12 and upon its lower edge a bottom flap 13which is secured to the said end flaps 12 in the customary manner. Theusual closing flap 14 is formed upon the upper edge of the body portion11 and is adapted when in its closed posit-ion to overlap the upperedges of the flaps 12 and 13. A plate 15 is secured to the outer side ofthe flap 13 and is provided with a central opening 16 of elongatedformation which registers with the slot 17 formed in the flap 13. Theplate 15 is formed with slots 18 arranged in spaced relation from theends of the said plate and from the opening 16, for the reception oflocking tongues 19 formed upon the opposite ends of a rectangular casing20 which is thus securedto the said plate 15.

It is readily seen that by the placing of the plate 15 on the outer sideof the flap 13 and the casing 20 on the inner side and the projection ofthe looking tongues 19 through the slots 18 of said plates 15 will actas clamping means for maintaining the flaps 13, 1212 in fixed assembledrelation.

In order to prevent any undesired displacement of the plate 15, a strip21 is secured to the under side of the flap 13 and to the rear side ofthe plate 15 and casing 20. A strip 22 of resilient material is securedto the inner side of the closing flap let as indicated by the numeral 23and this strip 22 is off-set as at 24: to produce a finger adapted whenthe flap 14 is in its closed position to pass through the openings 16and 17. The free terminal of this finger is bent backwardly at an angleto produce a resilient locking barb 25 the extremity of which is spaceda distance from the finger greater than the width of the slots 16 and 17to provide a means whereby when the finger is passed therethrough thebarb 25 will prevent any removal of the same thereby locking the closingflap in its closed posi tion.

It should be understood in this connection that various minor changes inthe details of construction can be resorted to within the scope of theappended claim without departing from or sacrificing any of theadvantages of the invention.

From the foregoing disclosures taken in connection with the accompanyingdrawing it will be manifest that a device of the nature described isprovided which will fulfil all of the necessary requirements of such adevice.

, Having thus fully described this invention what I claim as new anddesire to protect by Letters Patent, is:

The combination with an envelop provided with a bottom flap and aclosing flap;

of a plate secured to the inner side of the bottom flap, said plate andbottom flap being provided with registering openings and the plate beingfurther provided with spaced slots adjacent its ends, a rectangularcasing provided With looking tongues extending through said slots tosecure the easing to said plate, a strip secured to the underside of theplate, casing and bottom flap, end a latch member mounted on the closingflap and arranged to enter the openings and lock the closing flap andbottom flap together.

In testimony whereof, I a-fl ix my signature, in presence of tWoWitnesses.

WILBUR J. RINGER.
